Asus R9 Fury Strix OC Vmod Bios?

post #1 of 9
Thread Starter 
Hello,

I've unlocked my Fury Strix to 4096 shaders. But the voltage level is below the Fury X. 1,175 V (Fury) vs. 1,225 V (Strix). Now it should be clear, why overclocking and stability without issues is a problem.

There are no artifacts, but several driver shut downs in a variable time.

Could someone fix the Fury Strix bios with 1,225 V under load please?

Best regards

You would need to give us your BIOS (GPU BIOS). With this, you might be hardware locked and might not be able to get this as you would want.

Hi,

thank you very much for your post. Here is my bios:

1,25 V GPU load would be very fine thumb.gif.

Best regards

Is it possible to overvolt your GPU from BIOS?
If so, How to do that?
I'm right in your shoes, My fury unlocked to 4096 Shader units gives me artifacts frown.gif
Possible low Voltage problem? Or shall I roll back to 3840 Shader units and be dne with it?

What are your clocks with that voltage?

No, its no low voltage problem if you get artifacts. I have tested several Furys and artifacts means that the shaders are damaged. It's almost under windows in 2D and with one Sapphire Trix in 3D (Battlefield 4). You can use this bios with 4096 shaders (voltage control, only for Asus Fury Strix ) and the asus overclocking utility . I set the vcore of another Fury Strix to 1,3 V, but the artifacts are still there. So the only reason for artifacts are defective shaders, no low voltage. For more information click here.

If you have 4096 shaders no artifacts and you get stability problems it's caused by low voltage.

I don't know how I can modify the bios in order to get more voltage under 3D. With my currently bios i get 1,18 V under 3D (Firestrike Ultra). It isn't enough for 100 % 24/7 h stability and a bios is much better than using a tool. Remember the Fury X has 1,25 V stock voltage.

I thank you for your detailed answer, really helped me out and cleared alot of questions of my mind.
Then I'm sticking with 3840 Shader Units and that's already very satisfying as for free extra performance biggrin.gif
And I guess there isn't much difference from the 4096 Shader Units edition compared to a 3840 one anyway.
Only then the core clocks come into play and make the difference.

Thanks again, and I really wish others could benefit from this info as I have been looking all over the internet for these specific questions about the Strix version of Fury. smile.gif

Sorry, one more question!
Do driver updates interfere with the Shader Units count?
Experience crashes, revert changes or render only 3584 Shader Units usable?
